Title: Correction of shot position at charged particle beam exposure
Inventor: TAKEMURA HITOSHI
IPC: H01J37/304
Filed: 1983-03-31
Abstract: PURPOSE:To prevent charged particle beam exposure from generation of a slippage of position even when the sectional area of a charged particle beam is changed by a method wherein the slippages of the shot positions of the beams having the changed sectional areas are measured, and the difference thereof is divided by the difference between the functions of the respective sectional areas. CONSTITUTION:When a beam having the sectional area S10 starts to scan on a knife edge 8, a beam current signal detected by a detector 9 is differentiated respectively by differentiating circuits 14, 15. When a counter control circuit 16 detects the first peak of the output waveform of the circuit 15, a CPU4 stores the counted value A1 of a counter 17. Then the beam is made to have the sectional area S20 of size different from the sectional area S10 according to a beam sectional area variable device 3, the beam thereof is made to scan on the horizontal surface arranged with the edge 8, and the counted value A2 of the counter 17 is obtained by the way the same with the last time. Then the CPU4 subtracts the difference A1-A2 of the counted values from the reference value to compute the difference delta20-delta10 of the positional slippages of the sectional areas S20, S10, the quotient of the S20-S10 divided by the difference thereof is multiplied by a proportional constant, and the result thereof, namely the positional slippage of the beam center at a projection lens 6 is computed.

Title: Fuel cell
Inventor: TAMURA NIRO
IPC: H01M8/04
Filed: 1994-03-28
Abstract: PURPOSE:To further increase efficiency and lengthen the service life, make a fuel cell more compact, and reduce cost when steam demand is reduced in a steam utilizing device by arranging a control device to supply surplus steam generated by a steam separator to a reactor. CONSTITUTION:A control device 11 finds a necessary minimum steam quantity for a reactor 1 from a power generating load in a power generating part 2, and obtains a steam demand quantity from a steam utilizing device 6. The device 11 controls a flow rate control three-way valve 10 so as to send steam of a demand quantity of the device 6 when the steam generated from a steam separator 4 exceeds the sum total of the demand quantity of the device 6 as well as to send the residual whole of the steam generated from the separator 4 to the reactor 1. That is, the steam of a quantity exceeding a minimum necessary quantity is sent to the reactor 1, and the reaction to the steam proceeds in the direction for generating hydrogen. Thereby, since a hydrogen generating quantity to supplied fuel is increased, the same electric power is obtained by less fuel, so that power generating efficiency is improved. Since a radiator is made unnecessary, a fuel cell can be made compact, and cost can be reduced.

Title: Sigma-delta modulating circuit
Inventor: UMEDA KEISUKE
IPC: H03M7/32
Filed: 1988-03-11
Abstract: PURPOSE:To decrease the single-sound noises in a no-input state or a small signal input state by adding a signal having a spectrum out of the frequency band of an input signal to this signal to be applied to a 1st integration means. CONSTITUTION:The 1st and 2nd integration means 21 and 25 are connected in series in a system where the output of an adder 19 which receives an input signal X through one of its two input terminals is fed back to the other input terminal of the adder 19 after the delay of a prescribed degree. The output of the means 25 is roughly quantized and subtracted from the input signals to be applied to both means 21 and 25. Then a signal S having a spectrum outside the frequency band of the input signal to be applied to the means 21 is added to said input signal. Therefore the inputs of both means 21 and 25 have no fixed frequency in a no-input state or a small signal input state. Then the noise power spectra are evenly scattered and therefore the single-sound noises can be decreased in the audible bands.
